Egg Adhesion of the Codling Moth Cydia pomonella L. (Lepidoptera, Tortricidae) to Synthetic Substrates

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Previous studies on Cydia pomonella eggs have demonstrated reliable egg adhesion to the leaves and fruits of various apple cultivars. In contrast to biological substrates, this study is focused on standardised synthetic substrates to measure egg pull‐off forces and determine adhesive strength, allowing for an unbiased comparison with other ...

A Volatile Cue From a Specialist Herbivore Primes Gene Expression Against Biotic Stress in Tall Goldenrod (Solidago altissima L.)

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Insect‐derived molecular cues can prime plant defences against herbivore attack. The genes that are sensitive to priming, and how their expression changes on the scale of days, have not been fully resolved. Moreover, priming may affect interactions with insects that are not the source of the priming cue.

Morphological and biomechanical adaptations of larval mandibles in Trichoptera (Insecta)

open access: yesPhysiological Entomology, EarlyView.
Mandible morphology differs between predators and grazers: predators show pointed incisors, grazers sharp edges and setae. Mechanical properties depend on cuticle tanning, not elemental reinforcement. Functional mandible types reflect feeding strategies, with predators specialized for prey capture and grazers for scraping and collecting.

Neuromuscular Anatomy and Motor Patterns at the Base of Calling Behaviour in the Female Spongy Moth Lymantria dispar

open access: yesInsects

Nutrient landscape of a cricket nymph: How dietary protein and carbohydrate shape intake, performance, and body composition in the two‐spotted cricket, Gryllus bimaculatus

open access: yesPhysiological Entomology, EarlyView.
Survival of Gryllus bimaculatus nymphs was highest on protein‐biased diets (P:C = 3.86:1), whereas growth and body mass were maximized on slightly carbohydrate‐biased diets (P:C = 1:1.47). Maximum body protein and lipid contents were attained at P:C ratios of 1.14:1 and 1:5.56, respectively. When given a food choice, G. bimaculatus nymphs self‐selected
